Abstract:
Endoscopic submucosal dissection (ESD) is the gold standard technique for performing en bloc resection of large superficial tumors in the upper and lower gastrointestinal tract. It has not started in China until early 2006, when it was introduced at Endoscopy Center of Zhongshan Hospital. However, ESD is technically more difficult and can result in more complications, limiting its development in China. At present, reports about ESD training system in China are still not available. Therefore, our center continuously explored and gradually established structured training courses relied on the live pig model. Between 2009 and 2013, we held 23 hands-on ESD training workshops with 550 endoscopists. Questionnaires were distributed via e-mail, and there were 460 participants performing ESD in a step-up approach on the live pigs. More than one half of trainees could perform ESD with en bloc resection in the imaginary "lesion" of colon and stomach, and there were higher rates of hemorrhage and perforation occurring in colorectal ESD as compared to gastric ESD. After graduating from our hands-on workshop, up to over 90% of participants started ESD practice in their home hospitals. It was mostly provided by high-grade hospitals (IIIA) which played a major role as tertiary referral centers, covering almost all provinces and major cities in China. The training on live pig model revealed to be safe and effective as a prior step to its application in humans. It may enable novice endoscopists to acquire ESD skills and start performing ESD as soon as possible. The role of adequate training is of course to influence the spread of this technique and promote ESD development around China.
